SPECIFICATION forming part of Ltts Patent N0. 627,029, dated Jne 13, 189g. Application leci'ebruary 15, 1899. Serial No. '705,580- (Nonodel.)

To a/ZZ whom t may cm1/cern.-

Beit known that I, ALPHEUS FRENCH WAR- REN, a citizen of the United States, residing at Butler, in the county of Richland and State of Ohio, have invented new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention relates to the roller-bearings for the axles of car-Wheels and shafts gener- 1o ally; and its object is to provide animproved ,construction of the same which shall possess ysuperior advantages Wi th respect to efticien cy in use.

The invention consists in the novel con- I 5 struction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure lis a longitudinal section of a car-axle box provided With my improvements. Fig. 2 is a verco tical section on the line ai Fig. l.

In the said drawings the reference numeral l designates the main box, having a cylindrical bore in which iits a cylindrical sup; plemental box 2, provided at the outer end with a peripheral flange 3, which is secured to the main box by bolts 4.. Secured to the said supplemental box by countersunk screws 5 are wear-plates 6. Located in said supplemental box is a series of loose rollers 7 ,which go surround and bear against the journal 8 of a car-axle 9. This journal passes through openings in one end of the main box and the Wear-plate secured thereto. At the front side the supplemental box and its wear-plate are formed with openings 1l, which communicate Withan oil-feed reservoir l0, bolted to said supplemental box by bolts 12 and which is designed to contain a suitable lubricating material. Passing through the outer side of said oil-reservoir are set-screws 13, the inner 46 ends of which are formed with conical points adapted to engage with openings leading to the interior of the supplemental box.

In use the journal will rotate in contact with the rollers, whichlatter will revolve in the supplemental box, by which means the friction is reduced to a minimum. The supply of oil or lubricating material is regulated by the screw 15, by turning which the feed is increased or diminished, as the case may be.

Having thus fully described my invention, what I claim is;-

In a journal-bearing, the combination with the main box having a cylindrical bore and the journal, of the supplemental box fitting 55' in said main box closed at the outer end and provided with oil-openings in said closed end,- the iiange, the bolts securing it to the main box, the oil-reservoir secured to said supple mental box, the set-screws passing through 6o openings in the end of said supplcmentalbox, and having their inner ends reduced forming valves engaging with said oil-openings, the Wear-plates secured to said supplemental box and the loose rollers interposed between. said 65 journal and said supplemental box, substan= tially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALPHEUS FRENCH WARREN.
